DEFINITION

Classification: 384/490

Ball bearing:

(under subclass 456) Subject matter wherein the rolling friction is a spherical element.

(1) Note. This and indented subclasses includes bearing assembles or specified bearing components.

(2) Note. A spherical element has every part of its bearing surface equally distant form the center.
